Protons are made of two up quarks and one down quark, and have a charge of +e.
Neutrons are made of two down quarks and one up quark, and have a net charge of 0.
Electrons are fundamental particles, and have a charge of -e.

∙ 11y ago- The Atomic Number Says How Many Protons There Are In An Atom.
- The Atomic Number Also Tells You The Amount of Electrons As An Atom Has The Same Amount Of Protons And Electrons.
- To Find The Amount Of Neutrons All You Have TO Do Is Take The Atomic Number From The Mass Number Of The Atom. E.G Oxygen Has An Atomic Number Of 8 And A Mass Number Of 16 So 16 - 8 = 8 So There Are 8 Neutrons.

then,
No. of protons = Z
No. of Neutrons = A-Z
No. of electron in ground state = Z

How many protons does an atom have with a mass number of 43 and 21 electrons?
The atomic no. in this case 22, is equal to the no of protons and also electrons. So it has 22 protons and 22 electrons. The mass no. is equal to the no. of protons plus the no. of neutrons. So it has 22 protons and 26 neutrons. The metal with atomic no. 22 on the periodic table is titanium.
What does an elements atomic number represent-?
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)
How many electrons would you expect to find in a neutral atom containing three protons and four neutrons?
3
Find the Number of protons neutrons and electrons in xenon?
54 protons, an average of 77 neutrons, and 54 electrons.
Write the nuclide symbol for carbon-13?
Here is the isotopic notation for carbon 14. From looking at the isotopic notation, you can find the number of protons, neutrons and electrons in an atom. Protons- The atomic number is 6, so there are 6 protons Electrons- If the atom is neutral the number of protons equals the number of electrons, so there are also 6 electrons Neutrons- The mass number equals the number of protons + neutrons, and 14-6 leaves 8 neutrons 14 C 6
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
What particles make up the mass of an atom?
The number of protons
Do you have to add the protons and electrons in order to find the atomic mass of an atom?
no, you add the protons and neutrons
How do you find an atomic mass?
It is nothing but the total no of protons and electrons .So it is found by summing the total no protons and electrons present in an atom It is not electrons but the total of neutrons and protons present in the nucleus of any atom.
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
An atom of nitrogen has seven protons in its nucleus. How many electrons does it have?
Assuming that the atom has no charge, the atom will have seven electrons. If the atom is positive, you subtract the charge from the atomic number to find the number of electrons. If the atom is negative, you add the charge to the atomic number to find the number of electrons.
How do you figure out protons electrons neutrons?
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
How many protons does an atom have with a mass number of 43 and 21 electrons?
The atomic no. in this case 22, is equal to the no of protons and also electrons. So it has 22 protons and 22 electrons. The mass no. is equal to the no. of protons plus the no. of neutrons. So it has 22 protons and 26 neutrons. The metal with atomic no. 22 on the periodic table is titanium.
The center of an antom?
The center of an atom is the nucleus. Inside an atom you will find neutrons, electrons and protons. The nucleus is the most important part of an atom.
How many protons and electrons does a calcium atom have?
Calcium has 20 protons, 20 electrons and 20 neutrons in its most commonly found isotope.
How do you find the mass of electrons?
Nuclear Physicists don't really count electrons to have weight. An atom's mass comes from protons and neutrons.
A neutral atom always has what?
Atoms are mostly empty space. They do have a nucleus. This contains subatomic particles. Protons. neutrons, and electrons are all subatomic particles. Protons carry a positive charge. Neutrons carry a neutral charge Electrons carry a negative charge. You may want to see the Bhor/plum-pudding model for more information.
